Shims for Ball Bearing Housings

Image of System. Front orientation. Exploded view. Contains MultipleImages. Shims. Sold Individually, For Ball Bearing Housings, Round.

No need for keys, pins, or messy adhesives. These shims fit around the outer ring of your bearings for a secure hold in stamped, molded, or worn housings. All have ridges that press against the housing like a spring to keep the bearings in place. The ridges also dampen vibration for smooth operation, adjust for temperature fluctuations to maintain their grip, and compensate for up to 0.5° of misalignment. These shims are also known as tolerance rings.

18-8 Stainless Steel—The choice for wet and outdoor environments, these shims resist rust. However, they’ll corrode or pit when exposed to salt water and chemicals.
